IntelliJ UI unresponsive on each file analysis

I updated to the latest version of SonarLint for IntelliJ this morning, and now my IDE becomes totally frozen for 3-6s on each file analysis.

A thread dump shows that the EDT is trying to fetch data from the SonarQube server. See the two attached files:

thread-dump-1.txt (174.4 KB)
thread-dump-2.txt (105.4 KB)

My SonarQube server requires a client SSL certificate, which I did not configure in the IDE’s key store. Instead, I use a local proxy (Fiddler) that decrypts SSL connections to SonarQube and automatically authenticates requests. The UI freeze happens both when Fiddler is on or off (meaning even when SonarLint can reach the server, the UI is frozen). I don’t think my setup is directly related to the problem, this kind of analysis should probably be done in a background thread to account for “slow” server response times.
